If you enjoy gaming near-future Earth wars involving actual current nations that exist (not hypothetical countries or aliens), then who are your favorite to game with?

(For the purpose of this poll, I will accept some leeway as to future military forces such as a "Caucus Emirate" made up of several Islamic Caucus nations, a Slavic Balkan Coalition, the European Economic Community, the Commonwealth of Independent States, etc.).

This should be obvious, but as always let's try to avoid the politics and stick to gaming potentials.
